  • When Was the Last Time You Checked-Out Wolfram Alpha?

    Wolfram Alpha is not a traditional search engine — rather, it is a "computational knowledge engine".  That means it generates output from its own internal knowledge base, instead of searching the web and returning links.  Nonetheless, it produces some amazing answers to things you want to calculate or know about.

  • Why Some People Say PowerPoint Is the Biggest Enemy in the War Against Terror?

    Can a graphic that looks like a bowl of spaghetti help people understand a complex problem? 

    By now, you may have seen the “Afghanistan Stability” chart.  It is raising questions about the amount of time and effort spent on slides like these … and their point of diminishing returns.

    Isn't Lack of Thinking a Bigger Problem?

    So, is using PowerPoint (or some other tool) really dangerous?  Some claim it is because it can create the illusion of understanding and
    the illusion of control. Here are some interesting commentaries about that from the NYTimes and the comments from FlowingData.

    Do You Focus on the Process or the Result?

    Working on a PowerPoint presentation, mind map, data visualization, or even a business plan … all have something in common. In many respects, the process is more important than the product.

    When a chart (like the one below) is shown out-of-context, I wonder about its construction process. For example:

    • Was it the work of one person, a group, or collection of sub-groups each working on a different part and then coming together to see how what they did fits with the rest?
    • Was it based solely on one perspective, or did they come up with a reciprocal map that represents the other point of view … in order to come up with our plans?
    • Was this map designed to stand alone, or was it background data for a different discussion (I noticed that the slide was numbered 22, and we don't know what came before (or after) it, or how many slides there were in that deck)?

    OK, let's have some fun with the map.

    The Afghanistan Stability Chart.

    According to NBC News' Chief Foreign Correspondent, the goal in Afghanistan is to "convince militants to stop
    fighting and to persuade Afghans sitting on the fence—those unsure
    whether to back the Taliban or President Hamid Karzai’s government—to
    throw their support behind the U.S.-backed government and its security
    forces."

    Fair enough … But if you want to know how we plan to
    accomplish that feat, take a look at the large version of the military's
    amazingly complicated schematic (from the Office of the Joint Chiefs of
    Staff
    ) which outlines the entire strategy. The chart, at least, is a
    bit of a quagmire.

    “When we understand that slide, we’ll have won the war,” a General joked.

    Likewise, John Stewart has a few funny things to say on the subject.

  • Capitalogix Commentary for the Week of 05/24/10

    It's time to talk about American Idol (with the Finale this week, and all). 

    Sorry, my mistake … another bad jobs numbers came out & the markets went down … so it is time to talk about the American Idle.

    100523 American Idle Unemployment Cartoon

    Last week was rough for the bulls; and if not for a reversal after the opening bell on Friday, it would have been a lot worse. Consider this: The Russell 2000 gained 2.5% after the open on Friday and still finished with a 6.44% loss for the week. So, yes, it could have been a lot worse.

    Was That a Key Reversal Day in the Markets Last Friday?

    The S&P Index 500 technically complied with all the rules of a "key reversal day." It plunged to a new low of a significant decline. It then rallied up on increasing volume, and closed well above the prior close.

    100524 SP500
    And here is a longer-term chart showing the S&P on a weekly basis.

    100522 DShort-Serge-Perreault SP500 Weekly

    We will see if there is some buying triggered here.  If the bull-market swing is to continue it has to kick-in soon.

    But Where Is the Selling Pressure?

    With the market in a dizzying decline, why haven't we seen more committed bearish bets? Are traders going flat instead of short?

    One reason is discussed by Carl Swenlin. His assumption is that bull market declines will be short-lived, and that a neutral signal eliminates market exposure during a correction, while at the same time addressing the lower probability outcome of a full bear market decline. In other words, we never know if a bull market correction will actually be the beginning of a new bear market, but we do know that most of the time it won't be, so it makes sense to bet with the odds and go neutral.

    A Dash of Insight.

    I saw a list that I wanted to share.  It from the Dash
    of Insight blog
    , which is a consistently good source of information.  Here is an excerpt.

    "I am pretty fussy about economic news related to jobs and housing, and I did not like what I saw.

    • I closely watch building permits as the best leading indicator of new construction.  Construction is up (reflecting the tax credit, which has now expired) but building permits were down 11.5%.
    • The BLS report on Business Dynamics showed job losses for the quarter ending in Sept., 2009, were about 300K worse than expected.  You will not see this news anywhere else.  Even though this is an "old" report, people should watch it as a way of verifying the accuracy of the "official" BLS payroll employment report projections.  Basically, this is an early read on eventual "benchmark" revisions.  There was plenty of job creation, including a million jobs from new establishments, but still not as much as estimated.  More detail is beyond the scope of this weekly summary, but those interested can get the essentials of the argument in my analysis of the November report (different time, same issue).
    • The uptick in initial claims was also a negative for jobs.  We really need to see progress on reduced layoffs and more job creation.  Both seem to have stalled.
    • The S&P 500 broke the 200-day moving average.  Many people view this as the most important technical indicator, keeping them on the right side of major trends.  This is being quoted as 1102 or so, and is something to watch.
    • The ECRI indicators are in the growth area, but weaker than in past weeks.  Their interpretation?  "With WLI growth sinking further to a 43-week low, U.S. economic growth is set to start easing in fairly short order."  This seems to be an unusually strong emphasis on a "second derivative" interpretation of a strong reading, but it is their index.  I look at their numbers, but also at their own interpretation.

    The high volatility in trading is frightening to nearly all investors.  Thursday was especially bad.  The extremely late rally on options expiration day makes the week's pricing look a bit better, but most observers will need much more convincing."

    VIX Approaches Pre-2008 Record Highs

    The Volatility Index is spiking.

    100523 VIX
    When the VIX rises as it's done the past two weeks, emotions rule the market.

    Bill Luby found that, prior to 2008, the VIX only managed to nudge its way over a reading of 45 on three instances:

    The table below summarizes the top ten pre-2008 VIX closing highs. Last week’s VIX spike to 45.21 would put it at #3 all-time outside of the 2008 financial crisis.

    Will fear subside, or will volatility continue to soar? That will be one of the keys to the market worth watching next week.

  • How Did the Big Banks Really Score 100% Profitable Trading Days Last Quarter?

    100522 Perfect Quarter for GS
    The numbers are incredible.  Goldman Sachs just revealed in an SEC filing that its traders made money on every single
    trading day last quarter, a record for the firm. Net revenue for
    trading was $25 million or higher in all of the first quarter’s 63
    trading days with 35 of those days bringing in more $100 million. 

    Even if you had a 95% likelihood of a winning day, you would have
    only a 3.9% chance of doing it 63 trading sessions in a row. 

    Does a Perfect Trading Quarter Score One for the Rigged-Market Theory?

    Whatever the cause of the perfect quarter, it comes as part of a
    pattern. Goldman Sachs only recorded 11 loss days in the prior 12 months. So while some luck is
    involved in stringing together a perfect Quarter, the trend of success does not seem to be a fluke.

    It gets more curious, because it wasn't just Goldman.  Bank of America, Citigroup, and JPMorgan each also recorded a perfect quarter of trading profits.  What are the odds of that happening?  Apparently, pretty high under their current operating conditions.

    When the government is on a mission, you may not like the policies … but as an investor, you fight it at your peril. More simply put, don't fight the Fed. 

    It looks like the Banks figured that out. 

    Goldman figured it out sooner.

    100517 Heart Beat of the Markets
    Enticing the Crowd Back to the Markets With "You Can't Win If You Don't Play".

    After the "flash crash", the markets recovered quickly and then sold off again, ending that week with additional selling pressure. While some people might have seen that volatile move down as a buying opportunity, many others saw it as a place to get short (or at least to take some risk off the table).

    The result was heavier shorts and lighter longs going into the beginning of last week.

    For those of you that believe in the "Plunge Protection Team" (which isn't quite the same as believing in the Tooth Fairy), then it probably wasn't surprising to find the markets gapping higher to start trading last Monday. Nonetheless, you might have been surprised to find that the gap was close to 4%.

    100516 Gap Still Open
    It All Depends on How You Look At It.

    Once again, different types of traders will interpret that as a threat or an opportunity.

    The Bear:  Some consider "expecting gaps to close" to be a high probability trading setup. Consequently, a big gap-up offers an opportunity to enter a short position with a well defined stop. Add the increased volatility, and the bears were frothing at the mouth.

    The Bull:  This type of trader would notice that a 4% gap is very different than a half percent (or a even a one percent) gap. Consequently, they expect massive short covering from all the bears trapped in their short positions from the week before. Therefore, they are looking to buy the gap (instead of shorting it).

    Imagine the arguments at trading desks around the world as they try to figure out whether this pattern was part of a market top or the sign of a continuation rally.

    Obviously, the markets continued higher. This forced more shorts to
    cover, and also disturbed traders who wanted to buy, but didn't because
    of risk concerns.

    The Skeptic:  That brings up a third type of trader, someone who was sitting on cash because their trading systems work well during normal market conditions (but who suspects that these are not normal market conditions because of the volatility and exogenous threats).

    So, Wednesday comes and it is clear that the markets have been trending higher.  Now imagine the conversations at the trading desks of the people who are sitting-out these big swings. They are getting pressure from their bosses and their clients to ask why they are missing these "easy" trades.

    It's easy to go to cash, but when do you get back in? How do you determine when it's safe to get back in the water?

    Is It Safe?

    And there are signs that something "different" is happening.  Here is a video from Jason Leavitt.

    100517 Down Volume 

    Learned
    Behavior.

    Many of the algorithmic firms got burned
    during the last period of unusual volatility. They have the benefit of
    sophisticated back testing and analysis tools. You'd expect them to
    develop new rules to reduce their exposure, or at least a switch which
    systems are using in the markets.  So their behavior shouldn't be surprising.

    Pick Your Poison.

    Going back to the folks who believe in the Plunge Protection Team, as I've discussed before, it makes sense for the government to move the markets higher during periods of light trading. It accomplishes their goal with the least cost.

    Because it's supposedly a free market, if people disagree with higher prices … it will trigger selling. At this point, it appears that we are getting close to the area that will trigger selling.  Moreover, I don't think it is in the government's interest to prevent that from happening. Nonetheless, there is a lot of backstage maneuvering going on right now to prevent heavy selling.

    So traders now have a different decision in front of them. On one hand, they know it isn't often profitable to fight the Fed. On the other hand, in the long run, it's even harder to fight human nature. Markets can be pushed a little this way or that; but for how long?

    And our government isn't the only one facing tough choices.

    Greece Is The Word, At Least For A Little Longer … Then It Might Be PIIGS.

    Paul
    Kedrosky
    posted a chart showing that this time is different.  
    Behold the immensity and the singularity of Greece’s sovereign debt
    & fiscal adjustments.

    1005 Greece - This Time It Is Different

    Next, take a look at this.  The NYTimes came up with an interesting graphic depicting Europe's web of debt

    1005 NYTimes Greek Debt Overview

    As the Atlantic
    points out, it's not just the case that these countries are running
    huge deficits. It's also worrying that they owe each other tens of
    billions of dollars. Greece owes $10 billion to Portugal. Portugal owes
    $86 billion to Spain. Spain owes more than $200 billion to both France
    and Germany. If Greece defaults, it's not clear where the domino effect
    stops.
